Like if a cat runs down the road, or a mouse , or a bird flies by, they could be pretty quiet, but still go fast. What's the best (publicly) that humans can do, to make fast mobil robots, but that are also quiet ? For that matter how loud is a Tesla, if it's not pushing air.
What about motors in general, like how quiet can they make RC cars these days ? I can easily hear an electric 1 of them drive down the street, but I'd never hear a cat run down the street.
